One key to making portable devices more compact and energy efficient lies in the precise nanoscale form of energy-storing capacitors. Researchers in Sweden report they've cracked the challenge with a unique 3D printing method.
Researchers at KTH Royal Institute of Technology demonstrated a 3D printing method for fabricating glass micro-supercapacitors (MSCs) that reduces the complexity and time required to form the intricate nanoscale features MSCs need.
The advance could potentially lead to more compact and energy-efficient portable devices, including self-sustaining sensors, wearable devices and other Internet of Things applications, says Frank Niklaus, professor of micro- and nanosystems at KTH. Their study was published in ACS Nano.
